Bieber's own childhood wasn't a privileged one. His mom, Patti Mallette, gave birth to him when she was just a teenager and raised him primarily as a single parent. "I didn't have a lot. I grew up in geared-to-income housing. It was always rough for me," Bieber said. "We went to the food drive all the time. I always thought, 'If I ever get rich or famous, I will help people who are less fortunate than me.' This year I'm helping with the food drive in my hometown. I'm just trying to do as much as I can with everything I do."
